I am learning how to use with Zoho Sign API.

I am wondering if someone can give me a bare bones JSON data sample for "Send Document For Signature".

Below is the blank data that is pre-populated in postman.  Seems like there is more here than the bare minimum required.

When I send nothing for data, the API responds with the error message "  "message": "Add atleast one field for a signer.",

So obviously the bare minimum JASON in the date field is more than nothing.
